Hi,

I am trying to build a 2.6.35 kernel for i.MX31 and I am getting the following error:

  CC      arch/arm/plat-mxc/audmux-v2.o

/home/fabio/pengutronix/linux-2.6/arch/arm/include/asm/atomic.h:42: error: impossible constraint in 'asm'
make[1]: *** [kernel/sched.o] Error 1
make: *** [kernel] Error 2

I tried GCC4.3 and 4.4 and the result is the same. I haven't faced this issue when building 2.6.34.

Does anyone have any suggestion?

Thanks,
